Make works of art using a vintage yet effective etching strategy. The surface of a semiconductor chip has specific patterns formed through a process called etching. Through a lab investigation, young scholars recreate that process...

The moon is famous for its craters, but they haven't always been there. Young learners experiment with materials to simulate the creation of moon craters. Pupils are able to see patterns in their materials that are similar to the...

How do scientists determine when a solution is fully saturated? Scholars address the topic as they observe patterns of precipitation in various concentrations of ions. Using a well plate, pipette, and common chemicals, they collect data...

More than 70 percent of people and 90 percent of businesses use spreadsheets regularly. While many courses overlook the important skill, the simple water lab focuses on entering spreadsheet data, formatting it, and printing plots based...

Humans tend to huddle together when cold and move around more when warm, but do gas particles follow the same pattern? Scholars use a temperature probe, a pressure sensor, and air to study the relationship between temperature and gas...

As the most abundant element on the earth, hydrogen requires no replacement. Yet scholars learn to replace hydrogen with a metal to liberate the hydrogen gas. A simple procedure and data table include the necessary information and...

Who doesn't love gold and silver? Brine shrimp, that's who! Learners conduct an experimental lesson plan to monitor the toxicity of gold and silver nanoparticles on brine shrimp. They synthesize solutions to expose the brine shrimp to...

One way to study something is to try to replicate it. Young scientists do just that as they use solutions to recreate mineral structures on a dwarf planet. They make solutions with different types of salt, evaporate them, and observe the...

Investigate the procedure for developing computer chips! Learners use solar print paper to create both positive and negative images. They observe the effects of single and multiple exposures and compare results.

Harness young scientists' knowledge of genetics with an engaging science activity. Learners start by flipping a coin to determine the genotypes and phenotypes of two parent monsters, before using Punnett squares to...

The dynamics of a city can have a drastic effect on the weather. A hands-on lesson asks learners to build a model to illustrate how city pollution provides a nucleus for condensation. The greater the pollution, the greater chance for...

Have you ever wondered why golf balls have a pattern of dimples on their surface? The dimples are important for determining how air flows around the ball when it is in flight. The dimple pattern, combined with the spin imparted to the...

This website helps students work with word patterns by having them create limericks and sentences. Students receive feedback and guidance as they work their way through the activities.

In this activity, students will use Moire patterns to demonstrate wave interference.

Fingerprints are used as reliable identification because each person's fingerprints are unique. This lab allows you to research and discover if these unique patterns are created randomly or influenced by genetics.

A lab experiment in a series of experiments that explores droughts. In this lab, students analyze data to determine what a normal climate should be.

A lab experiment in a series of experiments that explores droughts. This lab has students looking at precipitation data to define what a drought and predict drought conditions.

In this project, you will investigate the physics of standing waves on guitar strings. You will learn about the different modes (i.e., patterns) of vibration that can be produced on a string, and you will figure out how to produce the...

This elegant project employs a scientific approach that is particularly valuable in Environmental Science, but can be applied to other areas as well. The approach has three steps: 1) from your observations in the field, form a...

You've probably noticed the colorful patterns "reflecting" from the shiny surface of a CD disk. What you are seeing is actually diffraction of white light, and the rainbows of color are diffraction patterns. In this project you'll learn...

Do you like to look up into the night sky? There are so many stars, it can be mind boggling. Some ancient people marked time by the changes in star patterns. We still use changes in constellation patterns to mark astronomical time. This...

In this project you can use archived satellite tracking data to learn about activity patterns of harbor porpoises. How far do they travel? Can you find patterns in the routes individual animals take? Can you correlate their route with...

Here's a project that looks at what the weather was like for over a hundred years. The goal of the project is to compare long-term precipitation patterns in different regions of the country. You will work with historical climate data,...

Did you ever notice the cool patterns around your footprints when you take a walk in the wet sand at the beach? The pressure of your feet has effects far outside your footprints. Here's a project that uses a simple experimental apparatus...
